内容記述 |
This paper deals with nature, age and disaster of the recent explosive activity of Changbai volcano in terms of tephrostratigraphic studies. The c. 1,000 yr.BP. eruption of Changbai should have been one of the greatest volcanisms in the world, because bulk volume of tephra erupted was over 50 km^3. The eruption reveals two distinct orderly progressions of activity, i.e., an initial silicic tephra falls followed by formation of large pyroclastic flow and the later, rather less silicic falls and flows, associated with debris avalanches and pyroclastic surge. The widespread ash fall deposit, B-Tm, is considered to be a combined product at the middle to late eruptive phases, forming a major component of all members. The magnitude of volcanic impact on human environments is exemplified by the extensive burial of forest under the pyroclastic flow, debris flow and Plinian fall deposits. |
